STMicroelectronics LIS2DUx12

The LIS2DU12, LIS2DUX12 and LIS2DUXS12 are smart, digital, 3-axis linear accelerometers whose MEMS and ASIC have been expressly designed to combine the lowest current consumption possible with features such as always-on anti-aliasing filtering. LIS2DUX12 and LIS2DUXS12 operate with a finite state machine (FSM) and machine learning core (MLC) with adaptive self-configuration (ASC). LIS2DUXS12 offers analog hub / Qvar sensing channel helping to define a new degree of system optimization.
